I've had a call with HR, and then I had to do a case study where I answered several questions. Days later I get an email saying that they are not moving forward with the process.

HR interview was nice and the mood was casual, however interviewer did not seem too interested. It was an easy conversation. The hiring manager talk was worse than this. He did not seem interested at all, he acted like he was in a hurry and our talk was interrupted a couple of times because of people coming in the room.
